I just bought a 24' used iMac.
The previous owner reinstalled Mavericks and sent it to me.
I looked at the disk usage info and it appears as if all the old data, movies, music, and everything else, is still there. Only 100gigs are free on a 500gig drive.
Is there a way to find this old data and reclaim my hard drive space?
I don't have a disk.
